trimmer shaft hinge with quick-release lever

Need a quick-release, like those found under bicycle seats, implemented with a hinge between shaft parts for quick folding and transportation. I am sure that pros would appreciate this feature, as would regular users--no need to put and remove 4 screws with 4 nuts--keep those in a bag as an option during shipping of new units.

As Paul said, the folding shaft is not designed to be folded continuously for storage. With the shaft folded the wires connecting the motor end with the battery end are exposed and vulnerable to damage. A "fold-to-store" design would need to take a completely different approach. Not impossible, though.
